Runtime error with gridview dll

[Jumma]

I am doing some testing with telerik gridview trial version.

I am trying to add the Telerik.Windows.Controls.GridView.dll in my Silverlight MVVM MEF application.
When I add the dll I get the following run time error:

03/05/2013 12:37:45:904: CRITICAL: Unhandled exception occurred:
Error loading module. ---> System.InvalidOperationException: The package downloaded successfully but an error occurred while reading the contents of the package. See the inner exception for more details. ---> System.Reflection.ReflectionTypeLoadException: Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information.

Hi,

Can you verify if you have other required dlls referenced? You can check also this article for more info.

Thanks for your reply.

I had the required dlls for RadGridView.
Telerik.Windows.Controls.GridView, Telerik.Windows.Data, Telerik.Windows.Controls.Input and Telerik.Windows.Controls.

Cheers

Hi,

 Unfortunately we are out of ideas what is causing this error at your end. Actually our own demos are built using MVVM and MEF however we have not seen such problems. 

All the best,
